Solution

The correct option is D $v_{2}$
Since, collision is perfectly elastic and $(m_{2} >> m_{1})$ ,
$m_{2}$ will continue its motion, with the same velocity.
So, velocity of $m_{2}$ after collision $= v_{2}$

Two balls of masses m1 and m2 such that (m2>>m1) are moving with initial velocities v1 and v2 respectively towards each other. The final velocity of m2 after collision will be [Assume collision to be perfectly elastic]

The correct option is D v2Since, collision is perfectly elastic and (m2>>m1), m2 will continue its motion, with the same velocity. So, velocity of m2 after collision =v2
